More Information
■Feature
· As the bearing inner rings protrude, there is no need to combine stepped shafts or collars for mounting.
· The urethane section is of a tire and wheel layered construction (Except for D20~D35 are single layer). Economical small diameter shafts can be used even for large diameter rollers.
· The bearings used have special configuration to prevent the urethane from detaching.
· Though it excels in oil resistance, applying solvents may cause swelling and reduction in strength.

Material Characteristics
It is important to select the right material according to your application, the different materials we handle within the catalog are
| Material | Description |
|---|---|
| Urethane | Excels in mechanical strength. Weak in heat and chemical resistance. Wide range of hardness variations. |
| Nitrile (NBR) | Excels in abrasion resistance and oil resistance, and economical. Inferior in weather resistance. Avoid using in areas where it may be exposed to direct sunlight or around ozone-generating electrical devices. |
| Chloroprene (CR) | Well-balanced in properties and economical. |
| Ethylene (EPDM) | Excels in weather resistance and economical. Inferior in oil resistance and fire resistance. |
| Butyl (IIR) | Excels in weather resistance and airtightness. Suited for inner tube of air tire. Inferior in oil resistance and fire resistance. |
| Fluorine (FPM) | Excels in most properties. |
| Silicone (SI) | Excels in heat resistance. Inferior in mechanical strength. |
| Low Elastic | Excels in shock absorption and oil resistance. Inferior in heat resistance and low temperature resistance. |
Comparison between Materials
The following is a comparison of the resistance of the materials:
| Weak |  | Strong | ||||||
|---|---|---|---|---|---|---|---|---|
| Mechanical Strength | Silicone | Low Elastic | Butyl | Ethylene | Nitrile | Fluorine | Chloroprene | Urethane |
| Weather Resistance | Nitrile | Low Elastic | Chloroprene | Urethane | Butyl | Silicone | Ethylene | Fluorine |
| Abrasion Resistance | Silicone | Low Elastic | Butyl | Ethylene | Chloroprene | Urethane | Nitrile | Fluorine |
| Heat Resistance | Low Elastic | Urethane | Nitrile | Chloroprene | Butyl | Ethylene | Silicone | Fluorine |
| Oil Resistance | Butyl | Ethylene | Silicone | Chloroprene | Urethane | Low Elastic | Nitrile | Fluorine |
Precautions
Urethane will change color and turn yellow over time.
Particularly antistatic urethane (gray color) may undergo noticeable discoloration, but, without physical problems and maintaining its properties.
The process of discoloration over time is shown below. Please consider this before use.
*Time and level of discoloration varies greatly depending on the environment of use, etc.

| Recommended Products | Press-fit bearing | Press-fit bearing | Lightweight: Press-fit bearings Heavyweight: Molded bearings | Molded bearing |
[!] The bearing urethane might come loose even if the bearing is used upward, sideways or downward, the bearing urethane can come loose. It happened because an unbalanced load is applied due to mounting accuracy, balancing of the workpiece, or it is used at high rotational speeds.
Way to Use
Heavy Load Bearings
- As the bearing inner rings protrude, there is no need to combine stepped shafts or collars for mounting.
- The bearings used have special configuration to prevent the urethane from detaching
- Though it excels in oil resistance, applying solvents may cause swelling and reduction in strength.
